A whetstone is considered by many chefs (and us!) to be the best way to sharpen a knife, as it sheds the least amount of metal from a knife while respecting the shape of the blade. Made of hard ceramics, this Japanese-made stone ensures speedy results and does not wear out easily. This is especially important for Japanese knives, which have tapered V-shaped edges. This Kai Seki Magoroku Combination Whetstone has a coarse 1000 grit for sharpening dull knives and a very fine 4000 grit on the other side for honing the edge. With this high grit, your knife may even be sharper than when it was new. The whetstone comes in a protective sleeve with its base providing stability while using.
